Description
A worn chain roller accelerates sprocket wear and introduces drivetrain slop that compromises power delivery and handling precision. The UFO Chain Roller for YZ250F/YZ450F replaces the stock unit with a reinforced injection-molded design that extends component life and maintains tight, predictable chain tension across aggressive riding conditions. Factory-sealed bearings keep contaminants out while delivering smooth, frictionless rotation.
